yes u can....
More than likely NO! My cousin was 6 months pregnant and her sister who was not took a pregnancy test to see if she were. The pregnant cousin got a negative result and the sister got a negative result. I would trust my doctor before a home pregnancy test. They do not always work.
I am not 100% sure what you mean by scan, but in my situation a pos test (both at home and the hospital) and nothing showing on the internal ultrasound confirmed an early miscarriage.
You are either really fat, or the home test is wrong. NEVER trust those things, go to a real Doctor and ask.
Oh yes! Tests are only about 85% accurate. And some conditions might cause the test to fail more often.
if only just pregnant then yes it wouldn't show up on a test
The easiest way to know if you are pregnant or not is to take a home pregnancy test or to see your Dr.
You are pregnant
if it says pregnate it could be a false positive meaning you could have cancer instead
That you're already pregnant!
You are pregnant
maybe that your pregnant and see your Doctor to confirm the test results.
A home pregnancy test is most likely to be accurate if it is positive meaning if you had a negative test you should be monitoring if you could be pregnant. You could have taken the home test too early to detect pregnancy. The best thing to do is to go to the doctor and get a test done there to rule out pregnancy.
